The VA usually enters the transverse foramen of the sixth cervical vertebra (C6), but an anomalous LVA originating from the aorta frequently enters at a higher level. In our series, ultrasound of the LVA showed entry at C4 in two patients and at C5 in one patient. These findings suggested anomalous LVA origin, and three-dimensional computed tomography demonstrated the LVA arising from the aorta proximal to the left subclavian arteries. Carotid duplex ultrasound is useful for the diagnosis of this anomaly.<\/jats:p>","DOI":"10.1177\/1971400916687585","type":"journal-article","created":{"date-parts":[[2017,1,7]],"date-time":"2017-01-07T11:15:52Z","timestamp":1483787752000},"page":"168-171","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Carotid ultrasound features of anomalous left vertebral artery originating from the aortic arch proximal to the left subclavian artery"],"prefix":"10.1177","volume":"30","author":[{"given":"Masayuki","family":"Wakita","sequence":"first","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ran","family":"Takei","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fumio","family":"Miyashita","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Hamada","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Ohyama","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideki","family":"Matsuoka","sequence":"additional","affiliation":[{"name":"Department of Cerebrovascular Medicine, Stroke Center, National Hospital Organization Kagoshima Medical Center, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Takashima","sequence":"additional","affiliation":[{"name":"Department of Neurology and Geriatrics, Kagoshima University Graduate School of Medical and Dental Sciences, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,1,6]]},"reference":[{"key":"bibr1-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1007\/BF00330136"},{"key":"bibr2-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1111\/j.1447-073X.2006.00133.x"},{"key":"bibr3-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-013-1142-0"},{"key":"bibr4-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1016\/j.aanat.2014.04.005"},{"key":"bibr5-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e31818938d1"},{"issue":"1","key":"bibr6-1971400916687585","first-page":"ONS20","volume":"59","author":"Bruneau M","year":"2006","journal-title":"Neurosurgery"},{"key":"bibr7-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-011-1549-3"},{"key":"bibr8-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.20013"},{"key":"bibr9-1971400916687585","first-page":"976","volume":"28","author":"Satti SR","year":"2007","journal-title":"AJNR Am J Neuroradiol"},{"key":"bibr10-1971400916687585","doi-asserted-by":"publisher","DOI":"10.2176\/nmc.41.8"},{"key":"bibr11-1971400916687585","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2005.01014.x"}],"container-title":["The Neuroradiology Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1971400916687585","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1971400916687585","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1971400916687585","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:33:28Z","timestamp":1777588408000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1971400916687585"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,6]]},"references-count":11,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2017,4]]}},"alternative-id":["10.1177\/1971400916687585"],"URL":"https:\/\/doi.org\/10.1177\/1971400916687585","relation":{},"ISSN":["1971-4009","2385-1996"],"issn-type":[{"value":"1971-4009","type":"print"},{"value":"2385-1996","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,1,6]]}}}
